函数名称：show_state_filter

函数原型：void show_state_filter(unsigned long state_filter)

返回类型：void

参数：

类型参数名称
unsigned longstate_filter
5991  printk(formational " task PC stack pid father\n")
5997  _read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other
5998  Careful: this is a double loop, 'break' won't work as expected. (g, p)
6006  h_nmi_watchdog - restart NMI watchdog timeout.* If the architecture supports the NMI watchdog, touch_nmi_watchdog()* may be used to reset the timeout - for code which intentionally* disables interrupts for a long time. This call is stateless.
6007  touch_all_softlockup_watchdogs()
6008  如果state_filter_match(state_filter, p)则sched_show_task(p)
6016  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
6020  如果非state_filter则debug_show_all_locks()
